In the Snowball.io world, you must survive in a fierce winter arena similar to Crowd City and Aquapark.io. Like these other two virtual worlds, you can participate as a anonymous participant in the arena. All names are set before entering the arena. Roll the snowball around in the arena to move faster. Colliding with another player in the arena will cause the snowball to grow in size, which will push the other ball backwards. If another enemy leaves the arena, they are out. After a set amount of time, the arena narrows similar to other survival games. However, this game is unique in that it squeezes between rounds. A giant iceberg serves as your arena. Icebergs gradually peter out until a victor manifests. The Snowball.io game doesn't feature many controls. All players need to do is swipe in the direction they want to move to control their character. After pouncing, players must press their finger to the screen to continue making a gigantic snowball. This must be held until it starts rolling and pushing the enemy away. Push your finger off the screen to launch a snowball. Deflect or collide with the snowball to choose your attack.

In addition to the point system and ranking system already in place, Snowball.io players can compete in a ranking system that results in their device's data being recorded. Playing the game increases your level, which means you come across more challenging opponents and tough wins. Try to use all your skills to become the best player you can be.

Snowball.io gives players many different costumes to collect. Some of these are superhero outfits, ninjas and snowmen. There are also Christmas themed costumes like Santa Claus and a snowball. Players can also collect fancy skins like penguins and a Ninja by collecting costumes that ride on vehicles of different colors. Because of these cool skins, many people want to play the game.

Snowball.io provides attractive visuals with a wide variety of characters that appeal to players. The game provides endless inspiration when playing by incorporating roll balls in each character's stride. Each character’s movement is well designed and aesthetically pleasing when engaging in a snowball fight.
